(6Z)-4-Bromo-6-{[(2-hydroxyethyl)amino]methylidene}cyclohexa-2,4-dien-1-one
The title mol-ecule, C(9)H(10)BrNO(2), excluding methyl-ene H atoms and the C-OH group, is essentially planar, with a maximum deviation of 0.037 (2) Å for the N atom. The N-C-C-O torsion angle is -63.1 (3)°. The mol-ecular structure is stabilized by a weak intra-molecular N-H⋯O(carbonyl) hydrogen bond, forming an S(6) motif. In the crystal, mol-ecules are linked by O-H⋯O and C-H⋯O hydrogen bond...
متن کامل6-(2-Hydroxyanilinomethylene)-4-nitrocyclohexa-2,4-dien-1-one
The molecule of the title compound, C(13)H(10)N(2)O(4), is nearly planar with a dihedral angle between the two aromatic rings of 2.24 (9)°. The NH group forms an intramolecular hydrogen bond with the carbonyl O atom. The mol-ecules form dimers about inversion centers in the crystal structure via inter-molecular O-H⋯O hydrogen bonds.

In the title compound, C(20)H(16)F(2)O(2), the cyclo-hex-2-en-1-one ring adopts a distorted envelope conformation and the dihedral angles between its six-atom mean plane and the fluorophenyl rings are 38.9(8) and 82.3(1)°. The two fluoro-phenyl rings are oriented at an angle of 77.3 (3)°. The long hy-droxy O-H bond length of 1.22 (3) and the H⋯O distance of 1.28 (3) Å, together with a longer th...

In the mol-ecule of the title compound, C(16)H(10)BrFO, the indane ring system is planar with a maximum deviation of 0.020 (3) Å. An intra-molecular C-H⋯O inter-action results in the formation of a planar ring, which is oriented at dihedral angles of 2.24 (3) and 2.34 (3)° with respect to the adjacent rings. π-π contacts between the benzene and indane rings [centroid-centroid distances = 3.699 ...
